Re: Moving data directory

No needs to specify in pg_ctl start/stop clause instead add a variable
in PATH. PG_DATA = d:\postgresdata\data. It is start by just typing
pg_ctl start/stop.
Thanks & Best Regards

Each time you start postgres server using pg_ctl you have to mention the

data directory location using -D option. Alternatively you can specify
in
the data_directory parameter of postgresql.conf file.
